My invention aims to provide improvements in separable snap fastener sockets and installations thereof.

' In the drawing which illustrates a preferred embodiment of my invention:-

' Figure 1 is a cross-sectional view showing one preferred form of socket and socket installation and a cooperating stud, the stud being shown in elevation;

Fig. 2 is a section through the parts of the socket installation shown in Figure 1 prior to assembly thereof;

' Fig. 3 is an under side plan view of the socket attaching member;

I Fig. i is a plan view of of the socket; and

Fig. 5 is a section through a modified form of socket installation.

- Referring to the embodiment of my invention illustrated by Figs. 1 through 4 I have shown a one-piece socket member (Figs. 2 and a) formed from sheet metal and having a support-engaging flange portion i of substantially U-shaped crosssection. The central portion is pressed out to form a. stud-receiving boss 2 ,closed at its upper end and open at its lower end to provide a studreceiving aperture. nected to the support-engaging flange portion i by walls 3 and d concentric with'and substantially parallel to the wall 5 of the boss 2. The socket is preferably of the yieldable type and therefore I have divided the walls 3 and it by slits t to permit yielding of those walls. The wall d tapers inwardly toward the stud-receiving aperture 3 and is connected to the wall 3 by a smoothly rounded portion i adapted to engage the neck ii of a cooperating stud t, as best shown in Figure l.

The wall 8 is preferably spaced from the wall b except adjacent to where it connects with the walls d so that there may be independent yielding of the walls 3 and h during engagement with or disengagement from the stud 9. The wall t preferably tapers outwardly away from the wall d from its point of engagement therewith so as to be spaced therefrom to permit movement of the wall 3 toward the wall A during yielding movement.

In the particular embodiment of my invention illustrated in Figure l, the socket is secured to a carrying medium or support it by the cooperation of an attaching plate ii carrying prongs it and the wall d and U-shaped flange portion i. The

the stud-receiving part prongs it carried by the attaching plate extend iii) at right angles to the general plane of the plate i i so that they may pass through the socket support it and engage the lJ-shaped flange portion i. The prongs i2 preferably extend from the inner edge of an inwardly bent flange is so that they are spaced a substantial distance inwardly from the plate i 9. Therefore, the prongs after passing The boss portion 2 is con--- through the support it come into contact with. the sloping surface of the wall t and are thereby turned outwardly and upset between the walls of the U-shaped flange portion i, as best illustrated in Figure 1. With this type of attaching means it is unnecessary previously to form apertures in the carrying medium or support it because the prongs are sharp pointed (Figs. 2 and 3) a and therefore pierce their own ways through the carrying medium. As a result, the support in is 10 gripped tightly between the attaching plate and the socket so that a very neat and durable attachment is provided.

The arrangement of the Walls 3, i and d with respect to each other and with respect to the flange portion i is such that after the socket is securely attached to the carrying medium or support it the yieldable walls 8 and d are protected against accidental distortion when the fastener is in use and when it is passed between the rolls of a wringer or the like during the laundering process of a garment to which the socket may be applied. Furthermore, the wall t back-supports both the wall and the wall 5 to prevent overexpansion and setting thereof.

Referring now to the modified form of my invention illustrated in Fig. 5, I have shown a socket member which is formed in substantially the same manner as that described in connection with Figs. 1 through 4. In this particular structure, however, I have shown a support-engaging flange it which is flat with the exception of the rolled edge it because the socket is attached by a rivet v rather than by attaching prongs. Therefore, with a rivet attachment it is unnecessary to provide the U-shaped clenching means provided on the first described form. v

The means of attachment isdifferent in the device shown in Fig. 5 and comprises a part it" having a tubular rivet portion ii extending centrally therefrom. The part it is provided with walls it and iii adjacent to the periphery there- 'by leaving a space to receive the carrying medium or support iii and a portion of the boss 2. The part it is preferably concealed by a cap member it secured thereto by rolling the edge underneath the walls it and it. The tubular rivet i'l may be of the self-piercing type so that when the attaching member and the socket are moved toward each other on opposite sides of the support it the rivet will pierce its own way through the carrying medium and enter an aperture it formed in thetop of the boss portion 2. Thereafter the end of the rivet ii is upset, as shown in Fig. 5, and the support it is gripped tightly between the cap it and flange it.

The concentric walls of the socket shown in Fig. 5 are the same in general so far as the walls 3 and d are concerned. However, since it is unnecessary to have the wall t imnerforate and 60 act as an anvil means, I have carried the slits 1 through the wall 4 to increase to some extent the over-all resiliency of the walls. Since the slits I terminate in tha flange I4, I have rolled the periphery of the flange ll back upon itself to provide a stiffened edge ll thereby strengthening the flange to such an extent that it is unlikely that the flange will crack or split adjacent to the ends of the slits 1 terminating'in the flange I 4.

While I have illustrated and described preferred embodiments of my invention, I do not wish to be limited thereby, because the scope of my invention is best defined by the following claims. a

I claim:

A snap fastener socket formed from sheet metal and having a support-engaging flange portion adjacent to the periphery, a central studreceivlng boss surrounding a stud-receiving aperture, said boss being located substantially entirely at one side of the plane of said supportengaging flange portion and a plurality of annularly arranged walls connecting said boss and flange portions, and said boss and at least oneof said annular walls being split to permit expansion and contraction of said boss adjacent to the stud-receiving aperture.

2. A snap fastener socket formed from sheet metal and having a central hollow boss surrounding a stud-receiving aperture, a pair of annular walls surrounding said boss, at least one of said walls and said boss being divided by a series of radial cuts to permit expansion and contraction of said boss for enlargement of the studreceiving aperture, and a support-engaging flange located outside of said walls and substantially in the plane of the stud-receiving aperture.

3. A snap fastener socket formed from sheet metal and having a central hollow boss portion surrounding a stud-receiving aperture, a pair of annular walls surrounding said boss, said boss and the wall nearest thereto being divided by slits to permit yielding movement thereof for enlargement of the stud-receiving aperture at one end of said boss, the other wall being imperforate and a support-engaging flange extending from said imperforate wall in substantially the same plane as the stud-receiving aperture.
